Characteristics of Living Things - What is Life?
extremophile microbes live deep in caves, and can be found as far as 1,000 feet below the surface. These microbes do not depend on the Sun for energy.

Characterization of existing mutagen-sensitive mutations:

character -- Heritable trait possessed by an organism; characters are usually described in terms of their states, for example: "hair present" vs. "hair absent," where "hair" is the character, and "present" and "absent" are its states.
Characteristics
Animals have several characteristics that set them apart from other living things. Animals are eukaryotic and usually multicellular[1] (although see Myxozoa), which separates them from bacteria and most protists.
Characteristics of Fungi
Most fungi grow as tubular filaments called hyphae. An interwoven mass of hyphae is called a mycelium.
The walls of hyphae are often strengthened with chitin, a polymer of N-acetylglucosamine.
Characteristics Common to All Living Organisms
Living things are composed of cells
Small organisms such as bacteria and many protists are composed of a single cell. Larger organisms are composed of many cells; they are multicellular.
Characteristics of X-linked Traits
1. Phenotypic expression more common in males
2. Sons cannot inherit the trait from their fathers, but daughters can.
character displacement
A phenomenon in which species that live together in the same environment tend to diverge in those characteristics that overlap; exemplified by Darwin's finches.
chemical bond ...
Character displacement: A pattern in which two species with overlapping ecological requirements differ more when they co-occur than when they do not.
Character displacement: Forced evolution of dissimilar characters in related species where their ranges overlap. Elsewhere, where they exist on their own, their similarities are maintained.
Characteristically, an HIV infection can progress for eight to ten years before the clinical syndrome (AIDS) occurs. The long latent period of the virus has contributed to many of the problems relating to diagnosis and control.
Characterised by, having the characteristics of, or containing a poison.
Synonym: toxic, toxicant, toxiferous, venenous.

- The observable characteristics of an organism as opposed to the set of genes it possesses (its genotype).The phenotype that an organism manifests is a result of both genetic and environmental factors.
Ammoniotelic Characteristic of organisms in which excess ammonia is directly secreted; many aquatic animals are ammoniotelic.
Trait is a specific characteristic of an individual. For example, their hair color or their blood type. Traits are determined by genes, and also they are determined by the interaction with the environment with genes.
Recessive gene. Characterized as having a phenotype expressed only when both copies of the gene are mutated or missing.
radial symmetry
Characterizing a body shaped like a pie or barrel, with many equal parts radiating outward like the spokes of a wheel; present in cnidarians and echinoderms.

Achondroplasia -- the most common and well known form of short limbed dwarfism characterized by a normal trunk size with disproportionally short arms and legs, and a disproportionally large head; autosomal dominant condition.
They have only longitudinal muscles and so have a characteristic whip-like motion. Most are free-living and some such as the hook worm are parasitic.

The term coined by Bateson and Saunders (1902) for characters which are alternative to one another in Mendelian inheritance (Gk. Allelon, one another; morphe, form).
The evolutionary history of the species¡ªwhich describes the characteristics of the various species from which it descended¡ªtogether with its genealogical relationship to every other species is known as its phylogeny.
That system grouped animals and plants by characteristics and relationships. Scientists looked at the characteristics (traits) that each organism had in common. They used the shared derived characteristics of organisms.
Transformed cells tend to exhibit characteristics known collectively as the "transformed phenotype" (rounded cell bodies, reduced attachment dependence, increased growth rate, loss of contact inhibition, etc).
Most eukaryotic genomes that have been characterized contain substantial amounts of junk DNA but most prokaryotic genomes that have been characterized contain less than 15% junk DNA.
It is concerned with the characteristics and behaviors of organisms, how species and individuals come into existence, and the interactions they have with each other and with their environment.
Within their characteristic long terminal repeats (LTRs), some retrotransposons encode retroviral-like proteins (e.g., gag, pol) for reverse transcriptase and integrase.
PRINTS The PRINTS database is a collection of protein fingerprints; conserved motifs characteristic of a protein family. Usually the motifs do not overlap, but are separated along a sequence, though they may be contiguous in 3D-space.
A gene that almost always results in a specific physical characteristic, for example, a disease, even though the patient's genome possesses only one copy.
Diatoms are very common unicellular algae that have a characteristic cell wall of silica. They exhibit a wide variety of shapes, some quite exquisite.

blind node. The first node formed on a strawberry runner that usually does not form a daughter plant.
A hereditary unit or a gene determines a particular characteristic in an organism and can be passed on unaltered to progenitors. It is located on a specific location of a chromosome. A gene may have multiple transcription units.
